Me too Wyn, in one sentence, you summed up why I love my job!

 

Question of the Week:   What Best Practices do we ignore

This week, they confess the best practices that they don't follow... be prepared for some shocks 😲.

Some sound pretty out there, but I agree with all of them (well, the Excel ones – no idea about the PowerBI ones!)  – as always, it’s all about context - which you’ll need to listen to get.

Mark

  • Uses Merge & Center
  • Doesn’t always use the simplest formula that he could

Sue

  • Sometimes uses calculated columns in PowerBI
  • Could be better at documentation

 Wyn

  • Separation of Inputs, workings and outputs
  • Doesn’t always hide unused columns and dimension keys in PowerBI
  • Needs to be better with accessibility
  • Doesn’t mark he calendar as a data table – which based on Sue’s response is very naughty!

Giles

  • You should always be prepared to bend the rules if it delivers a better outcome

 

🧢👕There is now Unpivot Merch : Unpivot Mech Shop

🧑‍🤝‍🧑The Unpivot team will be all together for the first time on May 20th at the Global Excel Summit.
